Has anyone used a flex fan on their 3.4 tacoma/01-04 tacomas? I'm not talking electric fan I'm talking bolt on flex fan. I've got one on my 66 mustang with no issue, but never used one on a daily driver. Any feed back? I'm reading reviews that elect fans can be a nightmare. Looking for a lighter less load option.

The fan clutch on the oem fan is designed to reduce load already; it stays loose until the temp rises.
The motor wasn't engineered to have a flex fan, so who knows how it would run. It might work fine...who knows.

well thats just it. I got one for my 66 mustang beacuase didnt want a elec fan. I wanted the car to look period correct or period correct mods. So i got one and pained it flat black an noone knows or pays attention. The cool thing is i live in the hottest part of Az so with it always throwing alot of air it sure helps the old cast iron small black to stay cool. Well that and the addition of a windage tray sure did seem like it gave teh engine some extra pep,well maybe not pep but smoother acceloration...Anyway,so in all honesty, why wouldnt itwork? I live about 45 min drive away from LC Engeering so i might get one form them and see how it goes. Its not that expensive of a mod and if it dont work ill just craigslist it. Some kid with a jerry rigged build will buy it.

i have actually looked into this and sorta in the realization and not really worth the effort the benefits dont come any where close to what the labor would be to install it. as KOCO said it has a clutch fan set up. but locating a spot for the coolant temp sensor is hard i thought about drilling into the water pump near the thermostat but the realized not F***in worth the time for 1-2 horsepower. i am still looking for another way i have pondered for the passed while because i got a deal on some fans and thought about splicing the relay into the temp sensor located into the back of the block but the voltage is different something like 3 volts when the relay is 6 volt, so that was a nogo. then thought about getting one of those temp sensor adaptors for the lower radiator hose but then thought about the relay reading late and having the posability of hurting the block. if you search and find another (easier) way definatley give me shout. P.S almost forgot you would have to set the circuit up through you A/C switch circuit so when you engage the A/C the fans will kick on if not you wont have cold air until A. you drive down the road/highway, or B. your fans kick on from the block getting hot and then the fans pull air through A/C condensor. kind of a hasel but if i find an easier way i will be sure to write a post bout it with pics and directions.

No you misread what I was looking to do. A FIXED flex fan. Like a real flexalite flex fan. NOT elect fan but a fixed lightweight alumn flex fan the flattens out at speed and retains shape at low rpms to throw air. Flexalite makes an elect fan but I'm not going near those. All the guys in the hot rod club have them and have nothing but problems, I put a fixed flex on my pony and she runs great.
